Managnese(II) selenide is an inorganic compound with the chemical formula MnSe. It is a dense gray solid that dissolves only by reaction.

Manganese(II) selenide can be synthesized by the reaction of selenium powder and manganese(II) acetate in an alkaline solution with a reducing agent such as hydrazine at 180°C. [1]

Manganese selenide exists in three polymorphs. Most common is the stable α-phase (NaCl type). [2] There is also a metastable γ-phase (wurtzite type) and an unstable β phase (zincblende type). [1]
